Consequently I first clean the line by calling backshlash several times as the exact length of the string is supposed not to be known. Next TileLeft is written. On R console one should, e.g., observe Time left = 0.3 sec.

Is there any reason you're not simply using \r ? The Mac GUI takes \b literally, supports full-document editing and you're simply backspacing beyond what you wrote.
